Is this true?
I don't think I will need it for towing my loaded 7000-7500# tt, but just in case I would need to, is it true this increases your capacities?
I'm assuming you already know this, but you focus here on the gearing, but you can't switch out an engine. Regardless of gearing, the 6.0 will only go so far, the 8.1 is a beast and will do a lot with the 3,73 and even more with the 4.1.
As far as payload. I have a 2006 with the 8.1 and 4.1's. My available payload is 2,100. We had to settle on getting one with some cosmetic dings, but got one with 49,000 miles and a Brakesmart controller for 18k. So, they are out there - but you have to look!
